Index of Biotic Integrity (IBI) Results:

An Index of Biotic Integrity (IBI) is a scientific tool used to identify and classify stream health. An IBI associates anthropogenic influences on a stream or with biological condition in the stream, and is formulated using data developed from biosurveys.
Details on the development and application of MBSS IBIs are in this document.
Fish IBI Fair - 3.7 / 5.0
Benthic IBI Fair - 3.0 / 5.0

Land Use

Land use can provide important information for determining stream health.

Physical Stream Habitat

Instream Habitat 11/20 (Suboptimal)
Epifaunal Substrate 9/20 (Marginal)
Velocity/Depth Diversity 5/20 (Poor)
Pool Quality
Pool Extent = 72 meters
10/20 (Marginal)
Riffle Quality
Riffle Extent = 3 meters
6/20 (Marginal)
Shading 85 %
Embeddedness 95 %
The embeddedness, a measure of silt on the stream bottom, was 95%. This is relatively high, and may exclude some biota.

pH (lab) 6.96
Alkalinity
(acid neutralizing capacity)
645.98 µeq/L
Dissolved organic carbon (DOC) 6.6679 mg/L

Biological Stream Condition:

Surveys of the organisms living within a stream can give indications of stream health. Species richness, or the number of different species present, as well as indicator species (species whose presence, absence or abundance can serve as a measure of environmental conditions) are informative for stream health.
